Poor baby The best thing I can think of is to separate Scout from the others. If you have enough space, give her her own room with food, litter box, toys, a cushy place to sleep, and, of course frequent visits from you, and keep the door closed at all times so none of the other critters can get in. Normally I'd never suggest shutting an animal up like that, but in this case it seems a better solution than keeping her out with the other cats and submitting her to constant harassment and beatings. Besides, she'd have all her things in the room with her, so she'd be ok.

As for Rocky, maybe you could ask your vet what might be causing his little leakage problem (could be he's stressed by the fighting).

I hope things get better at your house. It's hard to live in a place where family members are constantly at odds with each other--even if those family members are the pets.
